Abstract

A structure for suppressing flow vibration of an instrumentation guide tube, the structure being constructed such that an upper hole (37A) and a lower hole (37B) are formed at two upper and lower positions in a side face of the guide tube (27) and that a thimble tube (22) is pressed against the inner peripheral surface of the guide tube (27) by a difference between pressures of a cooling material in the inside and outside of the upper and lower hole (37A, 37B). Further, the structure desirably has an upper pressure regulation hole and lower pressure regulation hole formed at two upper and lower positions in a side face of an upper reactor core support column (21). The upper and lower pressure regulation holes allow a cooling material, having flown from the upper end of the guide tube into the guide tube, to flow from the inside to the outside of the guide tube through a gap between the thimble tube and the upper hole, flow from the inside to the outside of the upper reactor core support column through the upper pressure regulating hole, flow from the lower end of the guide tube into the guide tube, flow from the inside to the outside of the guide tube through a gap between the thimble tube and the lower hole, and then flow from the inside to the outside of the upper core reactor support column through the lower pressure regulating hole.
